: The science of cutting molds is a bit of an
: art form. The parts are ejected from the
: molds while still warm, and can have a bit
: of shrinkage. This shrinkage can be
: difficult to predict depending on the
: plastic used and the dimensions of the part.
: Mold design im itself is also a bit of an
: art as well, how the engineer decides to
: stack the dimensions can lead to errors in
: the overall dimension one decides to use as
: a metric for the scale, such as waterline
: length of the hull.
: The difference between 1/700 and 1/720 is
: significant. That between 1/700 and 1/702
: is probably within the margin of error
: within the molding/ tool design process. It
: is all not as easy as some would think.
